Screen stuttering, Power problem? Help!

So im watching a movie on my computer, a .avi, not a CD, so its on my computer. Now, lately, its been stuttering once every about 30 seconds... just a quick one, getting rele annoying. It gets worse wen i open an internet explorer window and keep resizing it over the movie, it stutters ALOT... so its almost a CPU problem. So, I also tried unplugging my power brick for some reason. When i did, i didnt have to do anything!... it just slowed the video down as the video kept going. As i plugged the brick back in, the video sped up and caught up with the sound!! WTF... i did change my video drivers to 175.12 the other day. I may switch back to 169.12... My power brick has also been failing lately, making noises... so, could it be failing causing this to happen? And how come wen i unplug it anyway, the video slows down?? cud it be a voltage thing with my video card or cpu... the other day i OVERoverclocked and my whole screen changed colors and i had to restart >_< could that have fried something? HELP

EDIT: adding: WTF, wen i unplug my power brick, the WHOLE computer get SLow as S**T... ?? this happen to anyone before?

 

OKay, that was a Waste of a post. I rolled back to 169.12... BAM fixed. I can open watever i want, and unplug the brick, and BAM! fixed, nothing even REMOTELY bothers the movie. How is this possible.... a video driver affecting wat seems to be CPU driven problem? i suppose this is more a general discussion than a Question... which also leads me to ask

wats the best new driver for a single 7950?? i thought 175.12 was official too!

okay now my computer almost froze while watching the movie.. but i somehow got windows media player to shut down... but... wtf again.. this is scaring me!

 

Buggy drivers will do all sorts of strange and bizarre things - as will perfectly good drivers that, for one reason or another, aren't properly installed (i.e., by the system, not you), get corrupted for one reason or another, depend on another piece of software that is buggy or corrupt, or even that weren't properly installed by you, namely, by first completely uninstalling the old driver first and using a wiping utility to remove all traces of the old driver.

At bottom, the problems you were seeing were not CPU-related so much as they were most likely related to bad hardware interrupt management, caused by any one of the things listed above. In other words, the queue of tasks needing to get done got too long, and finally a series of hardware interrupts came along that took priority over the video streaming, and took up so much time getting finished that the latency caused noticeable stuttering in the video. One culprit would be wireless and/or bluetooth, particularly if you're not using the connection but the module is on - in that case, the module is constantly polling to see if it can find a network, and each time it does that, it triggers a rather time-consuming h/w interrupt. Also, the amount of disk I/O going on in the background can cause enough of a delay to create visible stuttering, so it might have been a combination of a bad driver plus something like network polling or system indexing or even an anti-virus scan.

 

I had same problem with my system, turns out is not my notebook- exactly- when running avi on WMP it would get stuttering every 2-15 minutes, but VLC and KMP don't stutter at all, nor does Quicktime, when I have to use it. Needless to say I will never use WMP ever, ever again.

ever.

 

WMP is crap.
Use : KMPlayer, MPlayer, VLC, GomPlayer, and for codec packs :
-Ace mega codec packs
-Combined comunity codec packs
-KLite .

 

Check. Check. Double Check!
WMP= a tiny chunk of mucus that gets stuck in your throat when you have a cold.
KMP is my fav by far... love the interface and plethora of options.

 

Same stuttering happens with VLC... and in gaming like CoD4 which annoys me a lot as a gamer... Plus, it still gets a thousand times worse wen im battery. This is strange cuz my computer used to go just as fast while on battery like a month ago, while using my old 169.12 drivers, but now it does it either way. So how exactly do i COMPLETELY WIPE any and all driver residue, AND... wat drivers do ppl here recommend for the 7950!!

those are the two important questions i rele need answers.

 

1:uninstall driver
2:restart to safe mode (f8)
3:run driver sweeper; add bold text for shortcut to autorun i.e.("C:\Program Files (x86)\Driver Sweeper\G3DDS.exe" -nvidia -quit)
4:restart to normal mode
5:install new driver [if your old driver worked fine, whats wrong with going back to it?] some people say its better to install using "have disk" method but i think its BS.

 

i used drivercleaner.net to get rid of old drivers before i put the 175.16 so its not driver conflict. Im gonna go back to 169.12, BUT even before i do. Imagine i do this and this still occurs:

very little stuttering and games are playable while plugged in. THe MOMENT i unplug my computer, BAM, movies slow to a crawl (ON ALL players:KMplayer,WMplayer,VLC, etc..) and games stutter so bad my ping goes to 200 hundred and i cant play... then wat? Bad battery? bad voltage from bad battery? is it even a battery problem? or a fried video card (i overclocked it the other day until my screen went all different colors so i had to restart, but ive done that before to other computers and it cuzed no problems, and i can still play games so its not TOO Fried, but can a card be "a lil" fried?) battery?? vid. card??

 

card cannot be a little fried without you noticing... like my zd8000 that has a pink vertical line 1 pixel in width running 2 inches from the left side of screen...
I have not clue... but you said all this started after you installed that retarded driver so kick it's butt to the curb do a nice sweep and revert to the old drivers that WORKED and see if this helps at all.

 

yea... but wen i do that, even wen i sweep reaaaaallll good, with Driver cleaner.net and Driver sweeper... its still there now... not as bad.. but if i pull the plug... there goes me gaming!

 

I would probably stop using your power supply until you get a new one. If you mean it is making a high pitch noise or beeping I think that means it's not regulating the power properly. I speak from experience when this happened with my girlfriend's Packard bell laptop. She continued to use it while I researched where to buy a new power supply pack from and she fried her motherboard, could smell burning from the ports. it was only good for scavenging RAM, wireless card, and hard drive from it.

Google power packs and beeping and read the horror stories.

 

ok... but why does it affect my computer wen i UNPLUG... could it be a bad battery? (im getting a new power brick under warranty)

 

When you pull the ac adapter out, and check the status of the battery, what does it show?

It is possible for a bad ac adapter to damage the battery (as well as the system itself, if you're really unlucky). Just in case you want more detailed info, there's a utility called BatteryMon that should be able to show you more info on the condition of your battery than the standard monitoring utility in Windows can.

In any event, it sounds like you should definitely replace the ac adapter, and be prepared to replace the battery as well.

 

i tried to use the evaluation thing for it... ihave NO idea how to interpret these results

 

See if you can post 'em up, and we'll all take turns giving you the (probably wrong) interpretation of them.

 

wat do i even do? discharge the whole battery then send in the battery information log? I dont think its the battery as much tho.. I just went back to the OLD school drivers that CAME with my computer, 98.08. Problem SEEMs to be fixed, rele its not, it still stutters but MUCh less... but like i said, its still not a total fix.

 

Really sounds like something in your power properties, make sure you go in and set everything to high performance manually(office/desk not portable), then load the latest Sager drivers(174.90 I think), and another 2gb of ram wouldn't hurt either.

 

In order to play on battery , you`d have to force the power settings to adapt to maximum performance.
That would give you a good 30-45mins of gamin
Try NHC ,it can help.
Also , make sure the power option (the battery icon) is set for always on (xp) or max performance(Vista) , powermizer is disabled etc.

 

2 things to say about THAT!

- I went into properties and noticed that "on battery" the "minimum performance" for CPU was 5%... NO NO NO... changed that to a 100% immediately. Cuz basically, it would downclock me even while playing! that helped a little

-SECOND, POWERMIZER.. WTF! i have no options to screw with powermizer! SO, in the modded INFs of laptopvideo2go, i first changed the PowerMizerLevel and PowerMizerDefault to 1 instead of 3.... BAM SOOO much better while plugged in. but while playing on battery, it still stuttered to much to be able to play fine on battery! so, again i wiped drivers and went back to stock 98.08 drivers. Next time i install i may COMPLETELY wipe the section for powermizer registry keys. Supposedly it fixes the problem but my computer will get warm just surfing the internet...


SO BASCIALLY, were talking a heat problem + STUPID software making my beast computer cripple itself! BUT, guess wat im probably getting in a month... an NC2000 baby! so hold your horses hot cpu and gpu... ITS ON!

 

Using Xp would solve at least the heat issues

 

do NOT go there eleron!

 

Ha, been there , done that.
I`m switching to Vista soon , but (insert OS name here ) is still better at heat than Vista.
There

 

I mean, i still dont think its heat issue really, cuz there other day i removed the undersid of this thing and cleaned out A SOLID MAT OF DUST! between the fans and the heatsink... and it was working fine before that. the issue started randomly a week or two ago, and since then ive been trying everything to fix it! nothings rele working. just making things a little better...

OH and btw... ive been looking for a program to monitor my temperatures before i switch from 98.08 back to the 175 drivers to see if shutting off powermizer will make things hot. But RIvatuner and Ntune arent measuring my CPU or GPU temperatures... :-/ any1 got any programs that will... i think my computer dont have temp sensors...

 

I always have the drivers to blame.Most of the times, a clean reinstal does wonders.

 

of Vista? i hate reinstalling an OS, im not gonna do that till i upgrade my CPU and GPU, which will be after the 9800 pops out... first i need an external HDD to back up stuff too.... so, we'll see wat happens.

 

So you`re telling me you don`t have separate partitions for OS and stuff?
You have not been paying attention in classes ,young man,lol.

 

my thing came pre-installed, and NO i did not reformat the thing either to get rid of the junkware that came with... >_< i kno i kno.... im pretty sure they didnt cuz its not telling me on the C:/ drive. why does partitioning help again?

 

Ok, why partitioning is good:
1) OS 1 on one partition, OS 2 on 2nd partition, OS 3 on 3rd partition etc...
2) OS 1 partition is messed up for some reason(mbr damaged, boot sector drunk etc). OS1 wiped away, all the rest of the data, saved, hurray!
3) Reinstalling has never been easier! You have say 200 gigs of video ,music and pictures and games etc. But your OS is messed up,acting up on you,running like crap. Calls for drastic measures,reinstalling. So you wipe off(ie format) the bad partition and reinstall it, while all the pictures,games and pr0n(I`m sorry,movies ) are still safe and waiting for a new OS to use them.
4) Uhm, if you have more than 1 hdd, it`s awesome: Use a 32GB SSD for the OS system to make it lightning fast, and a regular 5400/7200 drive for everything else,as different partitions.

 

so upon reformat, in which ill drag all my important stuff to the external HD beforehand, how big should i make my vista ultimate x64 partition?

 

Xp should be ~20-30Gb, Vista should be 40-50Gb.
I mean, I`m pretty sure that you,just like myself and many others, install software into their default C:/program files folder, and that`s why I recommend those figures.

 

ummm lol my program files x86 and regular program files run me collectively 59 gigabytes... ALONE... so that PLUS my OS would be wat? lol

OH and btw... ive been looking for a program to monitor my temperatures before i switch from 98.08 back to the 175 drivers to see if shutting off powermizer will make things hot. But RIvatuner and Ntune arent measuring my CPU or GPU temperatures... :-/ any1 got any programs that will... i think my computer dont have temp sensors...

 

Well, then let`s put it this way:
15 Gb for XP and 40 Gb for Vista, + whatever you think you need for your software.
I read in tons of places that your OS partition should always be at least 10% free.

 

oh man.. a 100GB PARTITION FOR MY OS!!! ummm.. yeaaaaa... now i remember one reason i didnt use a partition cuz i dunno when i want to delete or remove soemthing cuz i need memory for something else. i only have a 160gb in this thing rite now.

ps. read my last part of my last post... i still need help with temp. watch.

 

HWMonitor should monitor everything - CPU, GPU ,HDD. It`s what I used for a very long time.
What do you mean Riva tuner is not showing temps correctly? Does it show 0C?

 

yessir it does show 0 degrees C

 

HWmonitor works... doesnt read my video card tho... just shows a picture of a monitor and ACPI.. im idling around 46 C.. thats about rite no?

thats weird, i noticed that another person using the HW monitor and they have the ACPI AND something that says 8800mGTX, and GPU temperature... i assumed the ACPI thing was that.. but apparently it isnt. SO, this program isnt monitoring my GPU either!

 

Yes.
Ok, in order to get Riva tuner to work do this :
Let me know how that turns out.

 

Hw monitor isnt working tho... and my card idles at 46-47. FN+1 drops me to 40 solid... actually.. 38.5 now...

 

So what is working now and what not ?

 

Rivatuner is working for my GPU cores... HW monitor is showing CPU, HDD, and ACPI (watever that is, cuz its not GPU: doesnt agree with rivatuner that is) no overlap tho. Meaning ill have to run two programs at once to monitor everything.

 

Welcome to my world.
There was a thread about making this programs run at startup, HWMonitor is easy, about the Riva Tuner, well that`s harder.
Also note 1 thing. When using Riva Tuner on the Default Monitor tab, you won`t be able to OC, you`ll have to switch back to PlugNPlay AFTER closing the temp monitoring window,or RT will crash.
I`ll have to dig into it and find out about that thread..

 

@Doodles: ACPI is the Advanced Configuration and Power Interface - in short, it is your overall CPU temp

 

aite.. with FN+1 i idled around 48 degrees playing CoD4. lets see wen i replace the drivers with the new 175s, with REMOVED powermizer registry values in the .INF... lets see if this fixes the problem at the cost of heat production... this should be interesting. BTW, even with these stock drivers, wen i remove the plug, still stutters ALOT!
